A warm thank you to the Hacker News community for all the conversation after the Outside Lands Festival, especially around how Tupac's voice was engineered for the Drake track. For those curious about the mechanics, here’s a breakdown of how a machine approaches this:

First, the machine analyzes the input by breaking the sound down into its core building blocks (spectral morphing) while also reading the text to map its emotional content. It then actively reshapes the audio by adjusting its rhythm and timing, creating an immersive soundscape, and adding nostalgic textures based on that emotion analysis. Finally, the system fine-tunes these changes and polishes the track to create the final, normalized audio output.

On a final note, I'll be at the AWS Builder's Loft in San Francisco today. Hope to see some of you there!

ps- we will not re-engineer Tupac's voice - thanks for sending your remixes!

I loved building alongside some talented and creative people this past weekend!

I created FanFunnels by the AI Homegirl. Outside Lands artists can instantly generate a QR code that they'll put on display during their set that allows fans to get a free exclusive from the artist, such as a free song. In exchange, the fans give their email and snap a picture real quick. It takes less than 30 seconds - the fan gets a song, the artist gets the fan's direct info + organic UGC content, and FanFunnels automatically sends out their free song, instantly nurturing the fan.

This solves the problem of artists not being able to capture their fans data (often due to privacy policies that venues and ticketing platforms have), easily collect and organize fan photos, and do it all on one simple platform (FanFunnels) in minutes.

Hey sugabush, thanks so much for sharing this!

I'm the creator of Memory Weaver. It was a huge honor to be selected—it's such an incredible community of builders.

For anyone curious, Memory Weaver is a web-based tool that transforms a written memory into a personalized soundscape. It uses psychoacoustic processing and emotion analysis, and the fun part is that it's 100% client-side. All audio generation happens in your browser with the Web Audio API.

Web App: https://memoryweaversoundscapes.lovable.app/ GitHub: https://github.com/ShaliniAnandaPhD/Memory_Weaver (with details and future roadmaps)

The project is still evolving, and I'd love to hear any feedback or ideas from the HN community. Happy to answer any questions about the tech!

Goal: build something for the Outside Lands attendees that folks would genuinely want to use at a music festival (where most would rather be dancing than on their phone)

Outside Cam turns your phone into a virtual photo booth that could land your photo on Outside Lands stage screens.

https://outside-cam.lovable.app/

Snap a photo → it reads your vibe and matches you with artists from the lineup to help you discover new music (use it for your post-show photo recap on IG and impress your friends with your music taste) → Submit to potentially appear on the big screens between sets

I built this solo in 3 hours as a non-techie & this was my first ever hackathon! I'm working on making it better and would love your feedback @spreadaioli on Tik Tok, Youtube, and Instagram :)

Everyone needs a great sound guy - but only the lucky few have one when they need them - until Auto Mix.

AutoMix is an AI Engineer that connects to your mixing console via OSC Protocol - used by over a hundred thousand of the most popular consoles like Behringer. It can be used as a copilot to save everyone from feedback and help route channels and in ear mixes, and soon as the sound engineer you wish you had at Front of House mixing in real time to match your genre and mix style.
